演示了一种远端驱动的旋转扫描微米内窥镜导管探头，用于超高分辨率体内内窥镜光学相干断层扫描（OCT）成像。与标准 OCT 成像探头相比，该探头允许调整焦距以实现不同深度组织形态的可视化，并具有更高的横向分辨率。远端驱动避免了其他探头设计中存在的不均匀扫描运动伪影，并且可以允许更广泛的成像速度。超高分辨率内窥镜成像在兔子身上得到证实
A distally actuated, rotational-scanning micrometer endoscope catheter probe is demonstrated for ultrahigh-resolution in vivo endoscopic optical coherence tomography (OCT) imaging. The probe permits focus adjustment for visualization of tissue morphology at varying depths with improved transverse resolution compared with standard OCT imaging probes. The distal actuation avoids nonuniform scanning motion artifacts that are present with other probe designs and can permit a wider range of imaging speeds. Ultrahigh-resolution endoscopic imaging is demonstrated in a rabbit with
